FRANK LESLIE CHRONISTER, OF EDMOND, OKLAHOMA.

TAPER GRAB.

To all whom it may concern Be it known that I, FRANK LESLIE CHRON-is'rnn, a citizen of the United States, and a resident of Edmond, in thecounty of Oklahoma and State of Oklahoma, have invented certain new anduseful Improvements in Taper Grabs, of which the following is aspecification.

My invention is an improvement in taper grabs, and has for its object toprovide a device of the character specified, which may be instantlyadjusted for the different sizes of wire, rope or cable, and which willfirmly grip said rope or cable, and which may be easily released whendesired.

In the drawings:

Figure 1 is a perspective view of the improved grab,

Fig. 2 is a similar view with the parts in another position,

Fig. 3 is a cross section.

The improved grab comprisesa body portion which is of tapering form, andof any suitable material, and at the small end of the body there isprovided an eye 2 with which is connected a ring 3 for permitting thegrab to be attached to a hoisting rope or the like. Upon the body thereis arranged a split ring 4, the said ring beingof a cross section suchthat it will not easily spread under strain. I

Referring to Fig. 3, it will be noticed that the body is longitudinallygrooved or channeled on one side as shown at 5 to receive a rope or wirecable indicated at 6, and the Specification of Letters Patent.

ring 5 has a transverse groove 7 on its inner edge which is adapted toregister with the groove 5. This groove 7 of the ring is directlyopposite the split.

Preferably the ends of the split rin are connected by a plate 9, whichis riveted to the said ends. The connection is a loose connection, sothat some relative movement of the ends is provided.

In use, with a rope or cable, the ring 4: is slipped toward the ring 3until the rope or cable 6 will pass between the ring and the body 1,lying in the groove 57. The ring 4 is then slipped down upon the body astar as it will go.

In use, with the wire 8, the wire is placed between the ring and thebody of the grab, and not in the groove 6.

I claim:

A taper grab comprising a body of tapering form, said body beingelongated and of circular cross section, one end being flattened andprovided with an aperture therein, a ring held in said aperture andadapted for attachment to a pull cable, said body having a smoothexternal surface and provided with a groove extending throughout thelength thereof at one of the sides of the flattened portion, a splitring mounted on the body and having a groove transversely at the insidethereof to register with the groove of the body, and a connecting memberbetween the ends of the ring.
